Leahy-Langridge image replacement with a fixed-size link
The problem: What is the best way to replace a link with an image, keeping the link target aligned with the image (using a wrapper div if desired, because it is not going to be removed from the markup regardless of what decisions I make here)?
I had previously tackled this with by styling both the link and a wrapper div, because it wasn't within the scope of the problem to remove the wrapper div that existed in the site template anyway. See http://codepen.io/m2bn/pen/xbgZJQ. In doing that, I decided it would be more streamlined to target only the
<a> anyway, even though the wrapper was still present in the code.
Here I'm trying the Leahy-Langridge technique (http://css-tricks.com/examples/ImageReplacement/) because it the markup is nice and clean.
CSS image replacement report card:
- CSS ON / Images ON: pass
- CSS ON / Images OFF: fail
- CSS OFF / Images ON: text only
- CSS OFF / Images OFF: pass
- Extra unnecessary markup: none
Conclusion: CSS ON / Images OFF would be preferable given the potential low-bandwidth applications of the site in question. Also, this technique requires box model fixes for older versions of IE, and IE 7 is in some use on this site.
Compatibility: didn't test, but CSS Tricks states that box model fixes are needed for old IE.
